For the numerical analysis of parabolic Neumann/Robin boundary control problems,
we refer the reader to
[1]}, [2]}, [3]}, [4]}. For the numerical
analysis of other optimal control problems for parabolic equations, we refer the
reader to
[5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}
and the references therein. Although the spatial discretization is not
considered in this paper, we would like to refer the reader to
[13]}, [14]}, [15]}, [16]} for the numerical
analysis of elliptic and parabolic equations with rough Dirichlet boundary data.
